IMPROVEMENT IN WATER-INDICATORS FOR BOILERS.

To A Lv WHOM IT .MAY CONCERN:

Be it known that I, AnsnoseG. FELL, of the city of Brooklyn, in the State of New Yorli, have invented a new and improved Water-Gauge for Steam 'Boilers; and do hereby declare the following to be a full, clear, and exactliescription thereof, reference being had to the drawings which accompany this specification and to the lcttersnnd figures marked thereon; Of these drawings- Figure 1 represents a front elevation of the gauge, and

Figure 2 a cross-section.

Water-gauges for steam boilers have been heretofore constructed with a glass tube, which is objectionable A for many reasons, such as liability to fracture from flying pieces of coal, from sudden changes of temperature,

and by'the crumbling or wearing away very rapidly at the ends, occasioned by the great heat these points are subject to and the corrosive efiects' of the steam thereon, besides the ivelI-knownliability to fracture after i cleaning. When a glass tube becomes broken it is necessary, especially on shipbo:ird, to replace it whilethe boiler is hot, consequently making the operation diflicult, having to work so close up to the boiler; and sometimes in breaking they son-id the men. It is found necessary with'glass gauges, when a. steamer is leaving-port,

' to carry along a a'bok full of tubes, because of the necessity of frequent replenishment. My gaugeis therefore more economical, as one will last as long as the boiler itself. Flying pieces of coal, great changes of temperature, &c. will not affect it; besides it will, being constructed in part of mice, stand' a greater pressurethan the gloss gauge, such hnving been found to be the fact by actual tests. I

To enable others to make and use my invention, I will proceed to describe itsconstruction.

A is the frame of the gauge cast with an adjiitnge or nozzle, a a, at each end for the attachments to the boiler. B Bare the faces or sides ot'the gauge, in each of which is a slotted opening running the whole length of the device so as to enable it person to look through the gauge. These faces or sides are firmly screwed into the frame A, perfect strips of mien, G C, of the same size as the sides B B, with thinstrips oi rubber or other suitable material, placed underneath and along the edges thcreoi',- being first inserted between.

The whole four faces or sides, or one face'alone, can be constructed with mica, if desired, but the arrangement here shown permits of aperson looking throughthe gauge as with the ordinary glass tube, though with the use of only one side of mica. the height of the water in the boiler is easily discerned.

What I claim as new, and desire to secure by Letters Patent, is-- l The construction of a wnter-indicutor for steam generators, having one or more sides of mica, substantially as and for the purpose herein set forth and described. i AMBROSE G. FELL.
